Description
When connecting to Couchbase Server using the couchbases:// scheme, and attempting to use a ClusterManager method, getMgmtEp() panics as the length of the cluster manager hosts is zero. It works OK when using the couchbase:// scheme.
A short repro:
func TestCouchbasesManager(t *testing.T) {
|
c, err := Connect("couchbases://foo.com,bar.com,baz.com")
|
if err != nil {
|
t.Fatalf("error from ac.FromConnStr: %v", err)
|
}
|
|
|
cm := c.Manager("Administrator", "password")
|
if cm == nil {
|
t.Fatalf("nil clusterManager")
|
}
|
|
|
_, err = cm.GetBuckets()
|
if err != nil {
|
t.Fatalf("error from GetBuckets: %v", err)
|
}
|
}
|
panic: invalid argument to Intn [recovered]
